A bigger rise from colder incoming water leaves the heater with less flow.
- Cold water
- Cold water must be at least 10°F colder than the hot water setting.
- Flow estimate
- The estimate uses the lowest certified flow among the listed models. It is about 1.5 gal/min at a 70°F rise.
Flow limits
- The estimate excludes the flow needed to turn the heater on, heat lost in pipes, and installation.
- Cold water from a well or long pipe run can differ from the temperature you enter.
- Without a stated flow limit, estimates for warmer water may exceed the heater’s actual flow.

Certified figures by listed model
| Model number | UEF | Flow at a 67°F rise (gal/min) | Recovery efficiency | Draw pattern |
|---|---|---|---|---|
| C2VS-160E 1** | 0.82 | 1.6 | 92% | — |

UEF is the uniform energy factor. A dash means the model has no such figure.
At a 67°F rise, its flow in the test is 1.6 gallons per minute. The median electric tankless model heats 0.7 gallons per minute by 67°F. Its flow at a 67°F rise trails 48 of the 337 electric tankless models.
In tests, 82% of the energy it uses ends up as hot water (UEF 0.82). Of the energy it spends heating water, 92% ends up in it (its recovery efficiency).
It is the basic model for C2VS-160E 1** and R2VS-160E 1**. All of its test figures are shared by 2 other basic models. The A. O. Smith and RELIANCE WATER HEATERS brands list one or more of them. For the full group, see the A. O. Smith R2VA-160E 1** page.
